Industry leading on renewable energy and energy efficiency.
Data centers are massive consumers of energy. This energy usage can have a major impact on the environment. Green Mountain therefore focuses on three questions: • What sort of energy do we use? • How efficiently do we use this energy? • How can we reuse the heat we are generating?
STATUS ON TARGETS: All our data centers are operated on renewable hydropower with a guarantee of origin. We have an ample supply of this renewable energy in Norway. When it comes to Power Usage Effectiveness, we hit our target of an average PUE of 1.2 in 2021. This was achieved by optimizing our cooling solutions to be as energy efficient as possible. However, it is worth mentioning that this PUE varies across our sites and client installations. The PUE is affected by the client’s IT infrastructure set-up in their respective data rooms and how they utilize their assigned power capacity. Cooperation between the client and Green Mountain ensures the best PUE possible. Our data centers produce a lot of heat that can be dispersed to air or water. This valuable source of energy is wasted. We know that this is not a sustainable way of operating and have therefore initiated two pilot projects to reuse the heat for onshore lobster and trout aquaculture farming. (Read more on page 40.)
NEXT STEPS: As we have ensured that all our sites use renewable energy, we are now focused on improving energy efficiency and implementing heat reuse programs. Although we advise our clients on energy optimization inside their data rooms, we want to make our approach more systematic. • We will establish an energy efficiency program and introduce it to all clients by the end of 2022 • We will continue to invest in our current heat reuse projects but will also explore new ways of efficient heat reuse. Our goal is to implement these solutions at all our sites. By the end of 2023, we expect to have at least one of these projects in operation • We will establish a pilot project for on-site wind and/ or solar power production by end of 2023 • We will focus on obtaining an ISO 50001 certification in 2023 (Energy Management System)
